&lt;!-- TWO STEPS TO INSTALL PYTHAGOREAN THEOREM:

  1.  Copy the coding into the HEAD of your HTML document
  2.  Add the last code into the BODY of your HTML document  --&gt;

&lt;!-- STEP ONE: Paste this code into the HEAD of your HTML document  --&gt;

&lt;SCRIPT LANGUAGE="JavaScript"&gt;

&lt;!-- This script and many more are available online free at --&gt;
&lt;! &gt;

&lt;!-- Begin
function solvepy(form) {
a = parseInt(form.a.value);
b = parseInt(form.b.value);
form.c.value = Math.sqrt(a*a + b*b);
}
//  End --&gt;
&lt;/script&gt;

&lt;!-- STEP TWO: Copy this code into the BODY of your HTML document  --&gt;

&lt;form&gt;

The Pythagorean Theorem
&lt;p&gt;
&lt;tt&gt;( a&lt;sup&gt;2&lt;/sup&gt; + b&lt;sup&gt;2&lt;/sup&gt; = c&lt;sup&gt;2&lt;/sup&gt; )&lt;/tt&gt;
